SHEET-MUSIC TURNER.

SPECIFICATION forming part of Letters Patent No. 602,127, dated April 12, 1898.

Application filed May '7, 1897. Serial No. 685,490. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. COMP, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Sheet-Music Turners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in sheet-music turners.

The invention has for its object the construction of a device for holding and turning the leaves of sheet-music.

With the above object in view the invention finally consists in the novel construction, combination, and arrangement of parts, as will be hereinafter more specifically described in detail.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals designate like parts, in which Figure 1 is an elevation of my improved music-leaf-turning device. Fig. 2 is a bottom plan view of the same. Fig. 3 is a side view of the trigger mechanism.

The device consists of a book-cover made of two separate parts 1 and 2, which are connected together at the top by a hinge 3 and at the bottom by the hinge 4. The pin 5, which forms a portion of the lower hinge, has a series of leaf-turning arms 6 pivoted upon it, and at the outer ends of the arms are formed clips 7 for holding the edges of musicsheets 8. A spring-trigger 9 is pivoted to the portion of the cover2,and has the hook 10 and pin 11 arranged upon it, and over the round ed portion of the trigger is loosely fitted the thumb-piece 12, which has a small opening 13 out within its lower portion, so that the finger-piece may be turn ed upwardly at right angles and connected fast to that end of the trigger by causing the small opening 13 to engage with the pin 11. A strap leis secured to the cover portion 2 and fits over the spring end of the trigger, so as to form a guard to prevent the trigger from moving past its points of operation. Each of the leaf-turning arms has a small opening 15 out within it, each of which is a little larger than the hook 10 of the trigger, and they are formed in such manner that the sides of every other one come opposite each other, as will be seen at Figs. 1 and 2, the object of which will be seen later. Each arm has secured thereto a spring 16, which is loosely wound a few times around the pin 5 of the lower hinge, and the springs are connected to the screws 17 at the opposite ends. By forming the springs in this manner the arms are placed in tension when they are held down by the trigger, and when they are released they are able to easily turn the leaves over to the opposite side. In order to hold the music-leaves within the cover, suitable clamps 18 are attached to the cover and clamped to the leaves and may be of any convenient form as will be most practical.

In the views shown the leaf-turners are all set for action and in operating the fingerpiece is turned upward and connected fast to the trigger, as described above. When it is desired to turn over the first leaf, the trigger is shoved over to the left a sufficient distance to bring the hook within the opening of the turner. The leaf-turner being thus released will turn over the leaf. hen another leaf is to be turned, the trigger is moved to the right a sufficient distance to release the second arm, and to release another the trigger is turned again to the left, &;c. When all the leaves have been turned and it is desired to reset the arms, the trigger is moved to the right a sufficient distance to be out of the way, as shown by dotted lines at Fig. 1. The leaf-turners are then replaced in the position as shown upon the drawings and the trigger moved over in its former position, as indicated by the full lines, and by turning down the finger-piece the cover may be closed.

In using the device upon apianoa suitable attachment may be connected to the trigger in such manner that it may extend down to the keyboard, so that by pressing upon akey the turners may be released, and in constructing the device any number of turners may be connected. When the cover is closed, the

springs are relieved of their tension, so that there is practically no strain upon them to cause them to get out of order.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a music-leaf turner, the combination with the two sections, the hinges at the upper and lower ends connecting them together, the arms pivoted on the pintle of said lower hinge, formed with a notch in the lower edge and provided with a clip at the outer end, and the springs for actuating said arms, of the spring-trigger pivoted to one of said sections, the hook intermediate the ends and the strap secured to said sections for limiting the movement of the trigger, substantially as described.

2. In a music-leaf turner, the combination with the two sections, the hinges at the upwith said pin and the strap for limiting the movement of the trigger, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES A. COMP.
